50 GEO. H. HORN, W. D. 



A. bicolor Lee. 



While on a visit to Mr. Ulke some months ago I had an opportunity 

 for the first time to examine the type of the above species. By a com- 

 parison of specimens I am inclined to suppress A. deserfns Horn as a 

 mere color variety. Some of my specimens collected at Fort Yuma have 

 the elytra decidedly brown but none are so dark as described by LeConte 

 and shown in the type. 



ISt'HIODONTUS Cand. 



An examination of the cabinet of Dr. LeConte showed that this genus 

 had been under study. There were, however, no notes left and the 

 arrangement of the specimens shows that he considered simplex Lee. and 

 ohlitus Cand. as synomyns of soleatus Say. In the synonymy he had 

 also included approximntus Cand., but I am sure the determination of 

 this species is incorrect, and it should for the present be stricken from 

 our lists. 



liEPTOSCHEHA n. g. 



This name is suggested for an insect described by me as Agriot.es 

 protractus (Trans. Am. Ent. Soo. 1871, p. 317). A more careful study 

 of this species, made necessary by a revision of Dr. LeConte's notes on 

 Agriotes, convinces me that it belongs to the Athoites as defined by 

 Candeze. The following are its characters: 



Head deeply inserted, somewhat deflexed ; front arcuate, the margin not prom- 

 inent but very distinct. Antennje slender feebly serrate, joints 2-3 small, equal 

 together very little longer than the fourth, 4-1 1 nearly equal in length. Prothorax 

 convex, the lateral margin entire, gradually deflexed in front, very nearly to the 

 inferior margin of the eye. Scutellum oval. Elytra elongate, obtuse at tip. 

 Prosternum distinctly lobed in front, the mucro slender and straight; lateral 

 sutures nearly straight, double, feebly excavated in front. Mesosternum declivous, 

 the margins of the fossa not prominent. Posterior coxae rather narrow, very 

 slightly wider internally, the inner angle very obtusely toothed. Legs slender. 

 Tarsi slender and simple, joints 1-4 decreasing in length, the first joint nearly as 

 long as the next two. 



This genus is closely related to Limonius and Athous, and like many 

 of the genera of the family is separated by feeble characters. With the 

 first it agrees in having the prosternal sutures double, it diff'ers in having 

 the legs and tarsi more slender, the first joint, especially of the posterior 

 tarsi, being much longer than the second. Athous has the the prosternal 

 sutures single, at least in our species.
